WINDERMERE, Fla. (Stockpickr) -- Professional traders running mutual funds and hedge funds don’t just look at a stock’s price moves; they also track big changes in volume activity. Many times when above average volume moves into equity it precedes a large spike in volatility.

Major moves in volume can signal unusual activity, such as insider buying or selling -- or buying or selling by “superinvestors.”

Unusual volume can also be a major signal that hedge funds and momentum traders are piling into a stock ahead of a catalyst. These types of traders like to get in well before a large spike, so it’s always a smart move to monitor unusual volume. That said, remember to combine trend and price action with unusual volume. Put them all together to help you decipher the next big trend for any stock.

With that in mid, let's take a look at several stocks rising on unusual volume today.

From a technical perspective, CONN is moving notably higher today on above average volume. This move is coming off of a near-term support zone at around $17 a share, and it’s now pushing CONN within range triggering a breakout trade. That trade will hit once CONN takes out some near-term overhead resistance at $19 to $19.83 with high-volume.

I would simply avoid or short CONN if it takes out that near-term support at $17 with high-volume.
